Ignition Coil Pack UF400 and Iridium Spark Plugs Set of 6 - Reliable

In this review of the UF400 ignition coil pack and 9807B-5517W iridium spark plug set, the bottom line is simple: this kit is for owners of compatible Acura MDX, Honda Pilot, Ridgeline and Saturn Vue models who need a cost-effective, like-for-like replacement to restore engine smoothness. The reviewer found the combination of silicon steel coils, Japan-imported rubber components and iridium electrodes produces dependable starting, improved throttle response and a clear reduction in misfires on worn engines, making it a practical repair option rather than a full service overhaul.

Key Features

• Direct fit compatibility: Designed to match factory fit for select Acura MDX, Honda Pilot, Ridgeline and Saturn Vue models so swapping old parts is straightforward.
• Durable coil construction: Coil packs use silicon steel cores and varnished wire to resist heat and prolong component life compared with lower-grade replacements.
• High-quality sealing: Japan-imported rubber helps maintain a tight seal at the boot, reducing moisture intrusion and electrical leakage.
• Iridium spark plugs: Iridium electrodes and ceramic insulators are specified to improve ignition stability and quicker starts on engines past 80,000 km.
• Warranty and support: The product includes a 12 month warranty and lifetime after-sales service for buyer confidence.
• OE reference checking: Multiple OE numbers and cross-references are provided to help ensure correct selection before purchase.

Who It's For

This kit is best for DIY owners and independent mechanics working on 3.5L V6 models listed in the fitment notes who need a straightforward replacement for worn coil packs and spark plugs to cure misfires, rough idling or poor acceleration. It is especially appropriate when the vehicle has over 80,000 km and symptoms include increased fuel consumption or hard starting.

It is not the best choice for buyers who need a vehicle-specific OEM part number verified by a dealership, or for engines outside the listed model years. Buyers who require a lifetime performance guarantee beyond the supplied warranty should consider dealer-original units.
